9514 1404 393

Answer:

  5/32768

Step-by-step explanation:

This sequence does not have a common difference, but does have a common ratio of r = 10/40 = 1/4. The first term is a1 = 40.

The general term of a geometric sequence is ...

  an = a1·r^(n-1)

Then the 10th term is ...

  a10 = 40·(1/4)^(10 -1) = 40/4^9 = 5/32768

Which statement is the most appropriate comparison of the spreads?
babunello [35]

Answer:

D  The IQR for town A is less than the IQR for town B

Step-by-step explanation:

A small IQR indicates that the points are closer together, while a larger IQR means that the points are scattered and that the plot is skewed in a certain direction. As you can see, town A's plot looks fairly balanced, while town B's plot is skewing to the left. Hope this helps :)
